Identifying and Operating the Massey Ferguson MF55 Articulated Loader

[MikePhua]

The MF55 and Its Historical Significance
The Massey Ferguson MF55 was a landmark in loader development, recognized as the first fully articulated wheel loader designed and built by Massey Ferguson. Released in the late 1960s, the MF55 marked a shift from rigid-frame designs to articulated steering, which allowed for tighter turning radii and improved maneuverability in confined workspaces. Massey Ferguson, originally founded in Canada and later headquartered in the UK, was already a global leader in agricultural machinery. The MF55 extended their reach into industrial and earthmoving sectors.
Powered by a Perkins AV8.510 V8 diesel engine, the MF55 delivered approximately 138 horsepower at the flywheel. This engine was known for its torque-rich performance and reliability, especially in cold climates. The loader’s operating weight was just under 30,000 pounds with the cab installed, and it featured a standard 2.5-yard bucket with a rated lift capacity of 12,450 pounds to full height.
Transmission and Mobility Features
The MF55 was equipped with a two-speed powershift transmission, offering high and low ranges in each gear. This allowed operators to switch between torque-heavy low gear for digging and high gear for roading. The top speed was approximately 21.1 mph, which was respectable for a machine of its size and era.
Some units included a rear axle disconnect feature, which improved fuel efficiency and reduced drivetrain wear during long-distance travel. Articulated steering was hydraulically actuated, and the loader’s frame pivot allowed for smooth navigation over uneven terrain.
Terminology:

• Powershift transmission: A gearbox that allows gear changes without clutching, using hydraulic actuators
  
• Articulated loader: A machine with a central pivot point allowing the front and rear frames to steer independently
  
• Rear axle disconnect: A feature that disengages the rear axle during transport to reduce wear and improve efficiency
  

Bucket Configuration and Modifications
While the MF55 originally came with a standard flat-edge bucket, some surviving units have been retrofitted with spade-nose buckets. These are typically used on larger loaders for penetrating dense material like rock or scrap piles. The presence of a spade-nose bucket on an MF55 may indicate aftermarket customization or repurposing for heavier-duty tasks.
Operators should verify bucket compatibility and ensure that hydraulic lift geometry remains within safe limits. Overloading or improper bucket sizing can strain the lift arms and reduce stability.
Parts Availability and Restoration Challenges
Today, sourcing parts for the MF55 is a significant challenge. Massey Ferguson’s industrial division was eventually phased out, and many components were discontinued. In regions like Finland, where the MF55 was never widely sold, finding replacement parts often requires international sourcing or custom fabrication.
Restoration tips:

• Identify engine components using Perkins part numbers
  
• Use hydraulic hose and seal kits from compatible models
  
• Fabricate bushings and pins locally if OEM parts are unavailable
  
• Consult vintage equipment forums and archives for technical manuals
  

Some restorers have successfully adapted parts from later Massey Ferguson loaders or even Hanomag models, though the MF55 predates Massey’s acquisition of Hanomag. The later MF55C, built after the merger, shares no major components with the original MF55.
Use Cases and Operator Experience
Despite its age, the MF55 remains a capable machine for yard work, scrap handling, and snow removal. One operator uses it to move scrap cars and metal, noting that its condition is surprisingly good for its age. The articulated steering and V8 engine provide ample power and maneuverability, even in winter conditions.
Operators should be cautious with hydraulic seals and electrical wiring, as age-related degradation can lead to leaks or shorts. Regular greasing, fluid checks, and cold-weather preparation are essential for reliable operation.
Conclusion
The Massey Ferguson MF55 is a rare but historically significant articulated loader that still holds value for operators and collectors. With its Perkins V8 engine, powershift transmission, and robust lift capacity, it was ahead of its time. While parts scarcity poses a challenge, the MF55’s mechanical simplicity and rugged design make it a viable candidate for restoration and light-duty use. In the world of vintage loaders, the MF55 stands as a testament to innovation, endurance, and the enduring appeal of well-built machinery.
